I watched a YouTube review by SkillUp on the full Lone Star set. He is of the opinion that the full Lone Star is the best set to get due to never having to reload - just swap between weapons. This means you are dealing almost constant damage.
It's an interesting review and worth the watch if you're interested in using Lone Star, or have an excess and don't know what to do with it.
